My invention relates to statistical machines, such as tabulating machines or other ofilce machines, and more particularly to statistical machines of the type in which provision is made for changing the machine from one operating condition to another, for instance from a condition in which the machine senses or interprets certain datarecorded by perforations on a card or strip and registers, prints, or otherwise analyzes such data, to a condition in which the machine is connected operatively with an adding mechanism or the like. The object of my invention is to provide a machine of this character which will require relatively little power for its operation, and in which excessive strains on parts of the mechanism are avoided, thus reducing wear and extending the life of the machine. Another advantage secured by my inventon is great accuracy in itsoperation, irrespective of long continued use.

Typical instances of means by which I secure these improved results, will now be described in detail, andthe novel features of the invention will then be pointed out in the appended claims.

In the drawings afiixed to my specification and forming part thereof several embodiments of my invention are illustrated by way of example. In the drawings Fig. 1 is a partial perspective view of a tabulating device provided for one denomination and based on the combination of four perforations, with the selector or feeler mechanism for the perforated cards pertaining thereto, and the mechanism for the group control,

Fig. 9 is a general wiring diagram of the machine.

At 1 I have indicated a perforated card which is fed by rolls'2, and provided with perforations which either singly or in combination designate or represent the digits from to 9.

These perforations are arranged in a plurality of groups 3 each having four squares or fields, such groups extending in the direction in which the card 1 is moved by the feed rolls 2. If it is desired to designate the value 1, a perforation is provided in the first square or field of the four field group 3, while for designating the values or digits 2, 4 or 8 the 2nd, 3rd or 4th field is perforated. when designating the values 3, 5 or 9 there is provided in addition to a perforation in the first field a second perforation in the 2nd, 3rd or 4th field respectively of the four-field'group, while the digits 6 or 7 would be represented by perforations in the 2nd and 3rd or 1st, 2nd and 3rd field respectively (see Fig. 6 of the drawings). In re ister with each group or column, there is provided a selector member, sensing element or lever 4 (Fig. 1) the end of which is in contact 75 with a card as the latter travels, and whenever such end meets a perforation, the lever 4 will swing on its pivot in such a way as to close a switch 5 which controls the circuit of an electromagnet 6 coordinated to the four-field group. Said circuit also contains a second switch 1 controlled by a rotary cam 8 and having for its purpose to cause the magnet 6 to be energized only at the particular moment desired.

The armature 9 of the electromagnet 6 is mounted upon a lever 12 which is pivotally connected with a lever 11 adapted to rock about a spindle and said lever 12 is provided with a transverse member 21. The levers 11, 12 are arranged to co-operate with a set of four control discs or segmental control members 13, 14, and 16 which are supported on pins 1'7, 18 and 19.

Of the four control discs the disc 13 is coordinated to the first field of any four field group 3 and thus to the digit or value '1, while the control discs 14, 15, 16 are coordinatedto the values 2, 4 and 8 respectively.

Each of the control discs is provided with a projection 13, 14 15 and 16 respectively. The upper or engaging surfaces of these four projections are substantially in the same plane when in their normal position, but they are located at different distances from the center or axis of the four discs, the projection 13 being nearest to such axis, and the projection 16 farthest therefrom. The transverse member 21 of the lever 12 will thus in succession be brought into co-operative relation to the individual control discs 13 to 16 through their control projections lit -16' if by he rotation ofa stepped cam 22 the lever 11 is rocked on its fulcrum 10 in a counter-clockwise direction against the resistance of a spring 11.

The shaft 4'7 on which the cam 22 is secured rigidly is connected operatively by suitable means (not shown) to rotate in synchronism with the feed rolls 2, so that the position of the cam relatively to the roller mounted on the lever 11 and engaged by said cam, will depend on the position of the card 1 relatively to the feed rolls 2.

The four control discs are held both in their inoperative position and in the position in which they have been shifted circumferentially upon a downward movement of the transverse member 21, by four pawls 23 which under the influence of four springs 24 are pressed into ratchet teeth provided upon the peripheries of the control discs.

With the four control discs 13, 14, 15, 16 is associated a type wheel 28 common to all of them, this wheel being provided at its periphery with types from zero to nine. The type wheel also carries pivotally a pawl controlled by a spring 29; when the type wheel turns, this pawl slides over the inner rim of all four control discs. The rotation of the type wheel 28 driven from a motor 73 (Fig. '7) through a friction clutch 74 is stopped as soon as the pawl reaches a position in registry with axially aligned notches 49 of the four control discs 13 to 16 and drops into such aligned notches. In the initial position illustrated, the pawl 30 is in engagement with the aligning initial or zero notches of the four control discs and thus holds the type wheel 28 against rotation. The notches 49, indicated in Fig. l, differ in their arrangement on each of the four control discs 13, 14, 15, 16 of the same set, as is shown in detail in Fig. 8, which illustrates clearly the axial alignment of the four zero notches in the initial position. According to Fig. "I, each friction clutch 74 consists of an elastic disc which presses the respective type wheel 28 against a collar '75 secured to the shaft 26 and thus produces the requisite friction. If desired, washers of oil-saturated felt, wood or other suitable material may be interposed between the elastic discs '74 and the adjoining collars '75. The shaft 26 is driven continuously by the motor 73 through suitable gearing, such as the toothed wheels 76, '77.

When the type wheel 28 is arrested by the pawl 30 as above referred to, a particular type will be in the printing position opposite the sheet 32 traveling in contact with guide rollers 31; the printing operation may be performed on said sheet with the aid of an ink ribbon 20 or in any other suitable manner.

Let us assume that the lever or sensing member 4, as the card 1 travels, comes into registry with a column or group corresponding to the digit value 1, in which case the card 1 has a perforation in the first field of the four-field group 3. In this case, the magnet 6 will be energized, through the operation of the switch 5, at the moment when (owing to the operative connection between the cam 22 and the card-feeding mechanism 2) the transverse member 21 is in registry with the projection 13' of the control disc 13 corresponding to the digit value 1. The downward movement imparted to said transverse member 21 by the armature 9 will shift the control disc 13 clockwise in Fig. 1, a distance corresponding to the length of the slots through which the stationary pins 17, 18, 19 project. In Fig. 8, the extent of this circumferential shifting of the control disc is indicated at a. By this movement of the con.- trol disc 13, the pawl 30 is raised out of the position shown in Fig. 1, that is, out of the bottom of a notch 49, since the notches of the four control discs are no longer in alignment. The type whee; 28 will consequently rotate clockwise by the distance of one unit, which partial rotation will bring the pawl 30 to a point where another notch on the shifted control disc (the notch numbered l in Fig. 8) 13 will be in alignment with three notches 49 on the other rings. The type wheel will then be locked by the pawl in the new position, and the type 1 facing the tabulating sheet 32 may then be printed by any suitable mechanism (not shown) while the type wheel 28 is stationary.

Fig. 8 shows the four control discs 13, 14, 15, 16 in a developed view, the vertical dotted lines, numbered from 0 to 9, being parallel to the axis of the shaft 26 and of the type wheel 28. Fig. 8 shows these control discs in the relative position which they have in the position of rest and it will be seen that in this position, the bottoms of the zero notches and only of these) are in axial registry with each other on all four control discs. In this position of rest, the pawl 30 is in engagement with said registering zero notches of all four control discs, said position of rest being also indicated it!) in Fig. 1. At a, Fig. 8 indicates the extent of the circumferential movement which downward movement of the lever 12 and its transverse member 21 will impart to one or another of the four control discs. From the description given above, 106 it will be evident that in the event of imparting circumferential movement to two or more of the control discs, the control discs will be moved or shifted successively, and not simultaneously. As soon as one of said discs is thus shifted from the 110 initial position, its zero notch will no longer register with the zero notches of the other three control discs, and by its shifting movement, said disc will move the pawl 30 out of the bottoms of the zero notches, thereby releasing the type wheel 28 for rotation by the respective friction clutch '14. This rotation continues until the pawl 30, carried along by the type wheel 28, again finds a set of notches 49 in axial registry on all four con trol discs, and by dropping into such registering notches, the pawl 30 will arrest the type wheel 28 in a definite predetermined position. If for instance only the control disc 13 is shifted circumferentially through the distance a, the notch of said disc immediately to the right of the zero notch will be brought into axial registry with the corresponding notches of the other three discs, in the position indicated by the dotted line 1, so that the type wheel 28 will be stopped after a partial rotation corresponding to one unit. The arrangement of the notches is different for each of the control discs, but is so devised that movement of one or more of these discs through the distance a will bring the bottoms of notches 49 into axial registry on all four discs at different positions indicated by the dotted lines numbered 1 to 9, so as to give the type wheel 28 partial rotations of the desired extent.

If the value 2 is to be printed, the card 1 will have a perforation in the second field of the fourfield group 3 and when such perforation registers with the end of the selector contact 5 the magnet 6 will be energized to swing the armature 9 and the levers 11, 12 so that the transverse member 21 will move downward.

As has been stated above, the shaft 47 carrying the cam 22 is operatively connected with the card-feeding mechanism, so that a. definite position in the travel of the card will correspond to each position of the shaft 4'7 and of the cam 22. 5C

It will be understood that as the shaft 47 is rocked, the steps of the cam 22 will swing the lever 11 to different positions, thereby shifting the transverse member 21 of the lever 12 into successive registry with the control projections 13, 14, 15 and 16, corresponding with the successive registry of the selector or sensing element 4 with the several fields or squares of a group or column of perforations. Thus, shortly before the end of the sensing element 4 drops into a perforation in the second field of the column, the cam 22 will have been brought, by the clockwise rocking of shaft 47, to such a position that its second step will be engaged by the roller on the lever 11, causing the transverse member 21 to register with the control projection 14 of the second control disc 14. In this particular case, therefore, the closing of the switch 5 by the sensing element 4 and the resulting energizing of the magnet 6 will cause the control disc 14 coordinated to the value 2 to be shifted clockwise and the type wheel 28 will be released from the holding action of the pawl 30 and will thus be allowed to be rotated by the friction clutch until such pawl again finds aligning notches in the four control rings, which will be the case after the type wheel has performed a partial rotation corresponding to two units.

To print the numbers 4 or 8 the control discs 15 or 16 respectively will be shifted in the same manner, while the printing of the numbers 3, 5 or 9 requires the shifting of the disc 14, 15 or 16 respectively in addition to the shifting of the control disc 13. From the above it will be understood that the relative position of the control discs and their position in relation to their inoperative position will vary according to the number or value to be printed, but will always be the same for tabulating or printing the same value.

For returning the shifted control discs to the position of rest the pin 18 mounted on the singlearmed lever 25 is. used. This lever is journaled upon the shaft 26 concentrically to the control discs and shortly before the completion of a tabulating or printing operation rocks in a counter-clockwise direction and back again under the control of a cam disc 27.

During this movement the pawl 30 and the type wheel 28 are first carried around in a counter-clockwise direction. The pawl 30 is, however, displaced from the bottoms of the notches 49 by the control disc which has remained in its inoperative position, and during the further rotation of the shaft 26 the type wheel 28 is again turned clockwise through the agency of the friction clutch '74, 75, until the pawl 30 reaches the inoperative position shown in Fig. 1 and is arrested therein.

Each of the four control discs 13 to 16 carries two extensions 33 by which double-armed control levers 34 provided for each of the control discs are adapted to be controlled which levers are fulcrumed independently of each other on a rod 35. V

The control levers 34 are provided with two notches 36, 37 adapted to be engaged by a rod 38 common to the four control levers coordinated to one column of the card, in dependence on the position of the control levers 34. This rod 33 is mounted in bell-crank levers 39 which in their turn are rigidly mounted on their spindle 64. This spindle is journaled in the one-armed levers 42 and these are adapted to oscillate about their stationary spindle 41 and are connected at their free ends by the rod 35 which forms the fulcrum of the control levers 34.

Between the two notches 36, 37 each lever 34 is provided with a tooth having inclined surfaces, and whenever a lever 34 swings on its fulcrum 35 to bring the rod 38 from one of said notches to the other, such tooth will lift the rod 38 for a moment and then drop it again. In the position of rest illustrated by Fig. 1, all the levers 34 are in such a position that the rod 38 is seated in their right-hand notches 3'1; the left hand ends of the levers are in such a position as to clear the left hand projections 33 when the levers 34 move downward with the rod 35, and the right hand ends of the levers 34, while above the right hand projections 33, are at such a distance therefrom that if the levers 34 move down in the pc:ition illustrated by Fig. 1, their right hand ends will not reach the right hand projections 33. If however any one of the control discs 13 to 16 is shifted clockwise as described, the left hand projection 33 of such shifted disc will be in the path of the left hand end of the corresponding lever 34, while the right hand projection 33 of the shifted disc will be clear of the path of the right hand end of said lever 34.

The bell-crank levers 39 are also connected by a rod 43 which on rocking of the bell-crank levers 39 controls a contact 44. The momentary lifting of the rod 38 closes said contact for a short while. This mechanism is utilized for exerting the group control in a manner to be described further on.

The one-armed levers 42 and thus the entire sensing device perform a counter-clockwise rocking about their spindle 41 when a pin 45 on the lever 42 drops into a notch 46 of a control disc 48 mounted on the shaft 47. The control shaft 4'7 is adapted to perform one complete revolution during each tabulating operation.

Fig. 2 shows the mechanism for changing the machine from one operative condition to another. The contact 44 for the control of the group shown in Fig. 1 is connected in series with the coil of an electromagnet 50. The armature 50 of this electromagnet is normally pulled away from the electromagnet by a spring 51 and is constructed as a shifting lever for the clutch member 53 which is slidable lengthwise of the shaft 52, but held to rotate therewith. On this shaft is mounted loosely, and held against longitudinal movement, a gear wheel 54 having clutch teeth to engage corresponding teeth on the clutch member 53. The clutch member 53 has another set of clutch teeth adapted to engage corresponding teeth on the hub 56 of a disc 57 mounted loosely on the shaft 52, but held against longitudinal movement. The shaft 52 is rotated continuously in any suitable manner as by means of an electric motor 55. By a sleeve 57, the disc 57 is connected rigidly with a gear wheel 59. The disc 57 is provided with a notch so as to operate a movable switch member to make or break a contact at 58 so as to keepthe circuit energizing the electromagnet 50 closed at certain times even after the circuit has been opened at the switch 44.

It will be seen that as long as the magnet 50 is not energized, the parts will be in the position illustracd, with the clutch member 53 in driving erative engagement with the hub 56 of the disc 57, thus driving said disc and the gear wheel 59 together with the meshing gear wheel 60 on the shaft 61, which latter causes a totalizing printing operation during one revolution of the gear wheel 59.

The device shown in Figs. 1 to 3 operates as follows: If the type wheel 28 associated with the control discs 13 to 16 tabulates or registers the value 1, for instance, a plurality of times, the control disc 13 will at each tabulating operation be shifted clockwise relatively to the other three discs 14, 15, 16. Before the value set up by the partial rotation of the type wheel 28, in the present case the value 1, has been printed on the paper, the control disc 48 releases the pin so that the levers 42 will rock counter-clockwise about their spindle 41. This movement is shared by the rod 35 rigidly connected with the levers 42 and thus the control levers 34 carried by said rod move in unison toward the peripheries of the corresponding control discs 13 to 16. At the first tabulation of the value 1 the left hand end of the control lever 34 associated with the control disc 13 (which disc has been shifted clockwise from the position shown in Fig. 1) will during the downward movement of said lever come in contact with the left hand projection of said shifted disc 13, and thus said lever 34 will be rocked clockwise on its fulcrum 35 and effect a momentary closing of the contact 44 as the rod 38 is lifted during its passage from the right hand notch 3'7 of said lever to the left hand notch 36 thereof. The clockwise rocking of this lever 34 lifts its left hand end relatively to the fulcrum rod 35, and lowers its right hand end relatively thereto. The other control levers 34, however, retain the position illustrated in Fig. 1 relatively to the control rod 38 common to all of them.

In the case assumed, where the value 1 is to be registered several times in succession, the position of the control levers 34' relatively to the control rod 38 will not be changed after the first of such registering or tabulating operations, since at each of these subsequent operations the control disc 13 alone is shifted, so that during the downward movement of the rod 35, the right hand projection 33 of the disc 13 will not be engaged by the right hand arm of the lever 34 associated with the said disc.

If after the tabulation has been completed in the manner described with reference to Fig. 1, the value 2 is, for instance, tabulated instead of the number 1, the operation will be similar, except that instead of the control disc 13 being shifted, the control disc 14 will be shifted. It will be remembered that during the operation described above the lever 34 associated with the control disc 13 has been left in a position in which the left hand notch 36 of said lever engages the rod 38, and in which (owing to the clockwise rocking imparted to the lever as set forth) its right hand end is lower than in its initial position. The control disc 13 is of course returned by suitable means, such as the cam 2'7, lever 25, and pin 18, to its normal position illustrated in Fig. 1, but the left hand end of the lever 34 will be in a position shifted clockwise about the rod 35, from the position illustrated, so that the right hand end of said lever will be nearer to the right hand projection of the control disc 13 than in Fig. 1. Therefore, when the rod 35 moves downward at the next sensing operation (assumed to be an operation in which the disc 14 has been shifted clockwise, while the disc 13 has been shifted back to the normal position shown), the right hand end of the lever 34 associated with the disc 13 will meet the right hand projection 33 of said disc and will thus be swung counter-clockwise on the fulcrum rod 35 thereby moving the control rod 38 out of engagement with the notch 36 and into the notch 37. This movement of the control rod 38 causes the circuit to be momentarily closed at the contact or switch 44, by the bell-crank levers 39 and their connecting rod 43. A similar action will take place if the lever 34 associated with the control disc 14 is rocked clockwise on the rod 35 when the latter is moved down after the control disc 14 has been shifted clockwise, the control rod 38 in this case coming out of engagement with the notch 37 and into engagement with the notch 36, the operation being of the same character as described above in connection with the clockwise rocking of the lever 34 associated with the control disc 13.

The closing of the switch 44 causes the energizing of the electromagnet so that the clutch member 53 is moved out of contact with the hub of the toothed wheel 54, thereby interrupting the drive of the card by the feed rolls 2 which takes place by means of the motor 55 through shaft 52,'coupling members 53, 54, gear wheel 62 and shaft 63. During the totalizing printing operation which follows, the card does not move, but remains in position for renewed co-operation with the sensing device when the feeding of the card is resumed.

Instead of operating the card conveying mechanism the motor 55 is now connected to the clutch member 56 so that the contact disc 5'7 performs a revolution which first effects the closure of the holding contact 58 for the clutchshifting magnet 50. The energizing of the magnet 50 is thus kept up for one complete revolution of the control disc 5'7 and during this revolution, the totalizing mechanism is operated by the shaft 61 through the gear wheels 59, 60 and carries out the totalizing and balancing of the tabulated amounts in any well-known or approved manner.

In Fig. 3 I have illustrated the electric connection of a considerable number of contacts 44 with the electromagnet 50 for changing the machine from one operating condition to the other. With each of the contacts 44, which on the one hand are connected to the positive pole of a source of current through a line 65, is connected in series a manual switch 66 of any suitable construction. To each of these manual switches 66 is assigned a perforation symbol row of the card 1 (Fig. 1) to be made use of for the group control, and in working the machine those manual switches 66 are closed the respective rows of card perforations of which contain the particular group characteristic to be registered, printed, or tabulated. It will be understood that each of the contacts or switches 44 co-operates with a separate group of instrumentalities (control discs, control levers, etc.) of the character shown in Fig. 1, and four such groups are indicated in Fig. '7. It is obvious that the closing of any one of the contacts 44 the manual switches of which are closed causes an energizing of the electromagnet 50 and thus the operation of printing the total or balancing. A drawback of the arrangement shown in Figs. 1 to 3 may be seen in the fact that a corresponding number of manual switches 66 have to be attended to if the statement of groups, the equality of which has to be supervised during the passage of the or a balance.

cording to Fig. 3, lever key switches 67 for three switching positions are provided for all but the first and the last switches. These lever switches may be of similar design to those customary in the art of telegraphy. The number of the switches 67 is by one greater than the number of the contacts 44. All these contacts are connected in series and the central springs of the lever key switches 67 are connected with this series-between two adjacent contacts 44, while all the left-hand outer springs 67* are electrically connected to a line 68 and through this line with the positive pole of a source of current, and all the right-handouter springs 67 are connected through a line 69 with a closed circuit relay 70.

By means of this arrangement it is possible to make use of any desired group of the contacts 44* for the group control by throwing the lever 72 of the switch 67 directly ahead of this group towards the right and the lever 72 of the switch 67 directly behind the group towards the left, whereby the respective central springs of the lever key switches 67 come in contact with their left-hand outer spring 67 or their right-hand outer spring 6'7 respectively. The opening of one of the contacts 44 located between the thrown-over lever key switches then causes the circuit of the closed circuit relay '10 to be broken momentarily and the relay to drop its armature 71 so that this armature closes the circuit for the electro-magnet. 50, in order to change the machine to the condition for printing the total According to both systems of connection (Figs. 3 and 5) it is easily possible to employ the item of a single column of a card or the items of one.

or a plurality of groups of card columns as a group characteristic and to supervise them automatically in order to tabulate the items contained on the cards in the event of the presence of like group characteristics, but in case of a change in the group characteristics to energize the elec-- tromagnet 50, asdescribed above. That is to say, as long as, during a series of successive operations each involving adownward movement of a fulcrum rod 35 and the levers 34 carried thereby, the position of the coresponding four control discs is the same at each of these opera-- tions as at the others, that position of the levers 34 relatively to theirfulcrum rod which has been established during the first downward movement of the levers 34, will remain unchanged during all the succeeding downward movements at which the control discsare in the same position as during such first downward movement. The switch 44 will therefore not be operated during these downwardmovements of the rod 35 after the first. If however at any downward movement of the rod 35, one or more of the levers 34 should find the corresponding control discs in a position different from the one that such control discs occupied during the preceding downward movement of the rod 35. such parti l lever or levers 34 will be rocked on the fulcrum rod 35 as described above, causing the switch 44 to be operated in such a way that the movable clutch member 53 will be shifted to change th machine from one operating condition to the other, as explained in connection with Figs. 2, 3, 5 and 9.

The control discs or control members 13, 14, 15, 16, in conjunction with the type wheel 28, constitute means for setting up the values determined or analyzed by the sensing means 4, while the levers 34 constitute means' for feeling or sensing the position of such setting up means 13, 14, 15, 16, through the co-operation of the ends of the levers 34 with the respective left hand and right hand projections 33 on said control members or setting up means. The switch 44 and the parts controlled thereby (including the clutch mechanism shown in Figs. 2 and 9) constitute a control mechanism, governed by'said feeling or sensing means (levers 34) to effect a change of the machine from the other.
